Abstract
In addition to concerns about mass concentrations of particulate matter in the
atmosphere, there are also concerns about specific chemical components (such as
transition metals). It is thought that these components may be responsible for
particular health end-points [I]. There are also plans to introduce stricter
mandatory EU particulate matter air quality standards for the year 2010 [2].
Consideration will need to be given to the contribution that natural materials may
make to these tighter limits.
In order to understand better the chemical composition of particulate matter and
the way in which this alters over time, this study collected a series of daily PMlo
filter samples from a coastal roadside site on the south coast of the UK. These
samples were subsequently weighed and then analysed using Scanning E
